Exotic hadrons in heavy ion collisions

TL;DR

This paper explores how heavy and exotic hadrons are produced and dissociate in heavy-ion collisions, focusing on the evolution of exotic states like the $X_{0,1}(2900)$ during the hadronic matter expansion.

Contribution

It provides a detailed analysis of the production and dissociation mechanisms of exotic hadrons in heavy-ion collisions, with a case study on the $X_{0,1}(2900)$ states.

Findings

Production and dissociation rates are significantly affected by the collision environment.

The time evolution of exotic hadron abundances can be modeled during the hadronic phase.

Recent experimental data on $X_{0,1}(2900)$ states are revisited in this context.

Abstract

Nucleus-nucleus collisions offer a great opportunity for analyzing and determining the intrinsic nature of heavy and exotic hadrons. In this sense, here we discuss how the production and dissociation of hadron states are affected by reactions during the expansion of hadronic matter in a heavy-ion collision environment. We give emphasis to recent works on exotic states, revisiting as a case study the time evolution of the abundances of the $X_{0,1}(2900)$ states.
